HARRY H. HISTAND, OF DOYLESTOWN, PENNSYLVANIA.

SNOW-GUARD To all 'whom it may concern:

Be it known that I, HARRY H. HisTAND, citizen of the United States, residing at Doylestown, in the county of Bucks and State of Pennsylvania, have invented certain .new and useful Improvements in Snow- Guards, of which. the following is a specification.

The obj ect of this invention is an improved. snow guard which is adapted to be attached. to a slate or shingle roof or the like and which is designed to prevent the snow from sliding off of the roof after thawing loose.

TWith this and other objects in view as will more fully appear as the description proceeds, the invention consists in certain conf structions and arrangements of parts that l shall hereinafter describe and clalm. y

For a full understanding of the invention and the merits thereof, reference is to be had to the following description and accompanyn ing drawings, in which:

Figure 1 is a perspective view of my improved snow guard. Fig. 2 is a front eleva tion thereof showing it applied. Fig. 3 is a side elevation thereof showing it in position upon a roof. Fig. l is a plan view.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawing by the same reference characters.

My improved snow guard is preferably constructed of an integral strip of wire or the like, comprising a main portion or shank 1, the rear end 2 of which is angularly disposed, extending downwardly therefrom and ta ering to a point. The other or front end o the main portion is bent to form an upwardly extending diamond-shaped abutment 3 the three upper corners of which are looped as shown at 4. The extremity vis then bent to form a ring-like foot 5 which lies in a plane substantially perpendicular to the lane of the loops 4 and extends forwardly om the abutment 3, said loop being elevated by the thickness of the wire above the main portion l.

Specification of Letters Patent.

Application led November 22, 1907.

In the application of my improved snow guard to a slate roof, the shank l thereof is I iitted in the joint between two adjacent l Patented Dec. 22, 1908.

serial No. 403,371.

slates of the same course with its front end extending upwardly from the margin portion of said slates and the rear end 2 extending downwardly through the cover portion thereof and being embedded in the sheathing of the roof to hold the device in lace. When the next course of slates is added, the por tion of the device positioned between the cover portions of the first-named course of slates will be hidden from view, thus leaving the front end of the device in the proper position upon the roof as shown.

The abutment 3 prevents the snow from sliding off of the roof after it has thawed loose, the loops 4 of said abutment serving to ornament it and. also to stiffen it. The foot 5 rests on the adjacent portions of the two slates, as is permitted by its elevation above the main portion l, and forms a relatively large bearing surface which serves as a brace for the abutment to assist the latter in withstanding the strain. exerted thereon by the weight of the melting snow.

lt is to be understood that this improved snow guard is described and shown as ap plied to a slate roof for the pur ose of illustration only and that it is equal y applicable to shingle roofs or the like.

Having thus described the invention, what l claim is:

The hereindescribed snow guard con* structed of an integral stri comprising a shank, the rear end of whic is bent downwardly and the forward end of which is 01ppositely disposed to form an abutment, t e forward extremity of the strip being bent to `form a loop lying in a plane perpendicular to the plane of the abutment and constituting a foot, said foot being raised above the shank and extending forwardly from the abutment, so as to form a bearing surface to bracethe latter and coperate with the rear end of the strip to secure the device firmly in position.

In testimony whereof l affix my signature in presence of two Witnesses.

HARRY H. HISTAND.
